Why you need a professional api integration development partner
Building API integrations in-house often takes twice as long and costs more than expected.
A professional API integration development partner like IRPR brings battle-tested patterns for authentication, rate limiting, retries, and data transformation. Our team has completed over 200 integrations for clients in 50 countries. We use Node.js, Python, and Go to build integrations that handle millions of API calls per month.
Integrations fail when they lack proper error handling or monitoring. Every integration we build includes Sentry error tracking and Datadog monitoring out of the box. You get a fully documented API that your team can maintain.
How we differ from other api integration shops
Most agencies sell you a team of junior developers who learn on your dime. IRPR sends senior engineers who deliver on day one.
When you work with IRPR as your professional API integration development partner, you get a fixed price and a clear timeline. We write all the code in your repository from the start. There are no black boxes and no legacy code dumps.
We also build to your compliance requirements. For healthcare, we follow HIPAA rules. For fintech, we meet PCI-DSS level 1 standards. For SaaS, we align with SOC 2 controls.
- Assigns junior developers with no API specialization
- Charges hourly with no cap
- Delivers undocumented code
- No error handling or monitoring
- Takes 16-24 weeks for a simple sync
- Does not enforce compliance
- Senior engineers with 10+ years API experience
- Fixed price from $80K
- Full documentation and tests included
- Sentry and Datadog by default
- 8-12 week delivery
- HIPAA, PCI-DSS, SOC 2 compliant
Our process for building your api integration
We follow a four-phase process that derisks your project at every step.
Every integration starts with a discovery call where we map your data flows and endpoints. Then we build a Roadmap document with exact scope and fixed quote.
After your approval, we build the integration in two-week sprints with regular demos. The final phase is production release with monitoring and a 30-day warranty.
What ships with every api integration engagement
Every integration is a complete solution, not just code.
You get more than a working connection. Every deliverable includes documentation, tests, and monitoring. Your team can extend the integration without calling us.
- Source code in your private GitHub or GitLab repository
- Automated tests with 90%+ coverage using Jest or pytest
- API documentation in OpenAPI 3.0 format
- CI/CD pipeline using GitHub Actions or CircleCI
- Sentry error tracking for production alerts
- Datadog dashboards for latency and error rates
- Deployment scripts for AWS, GCP, or Azure
- Postman collection for manual testing
- 30-day post-release warranty
What we ship in this practice.
Stripe to NetSuite sync
A SaaS company needed daily reconciliation of Stripe payments and refunds into NetSuite. We built a Node.js service using the Stripe API and NetSuite RESTlets. Reduced manual reconciliation from 10 hours per week to zero.
Salesforce to HubSpot contact sync
A B2B sales team had leads in both Salesforce and HubSpot with no synchronization. We built a bidirectional sync using Python and Airbyte. Lead duplication dropped by 95% and reps saved 6 hours per week.
Epic EHR to custom patient portal
A healthcare startup needed real-time patient data from Epic. We used FHIR APIs and HIPAA-compliant architecture. Patients now see lab results within minutes of release instead of 24 hours.
Shopify to ERP order sync
A multi-channel retailer processed orders from 3 Shopify stores into a single ERP. We built a Go-based webhook receiver that writes orders in under 2 seconds. Order processing errors dropped from 8% to 0.2%.
Twilio SMS to CRM workflow
A logistics company wanted automated SMS alerts to customers from their CRM. We connected Twilio to Salesforce using webhooks and built a custom routing engine. Customers receive delivery updates in under 5 seconds.
Amazon S3 to Redshift data pipeline
A media company needed to move terabytes of analytics data daily from S3 to Redshift. We built an AWS Lambda pipeline using Python and Glue. Data latency dropped from 12 hours to 30 minutes.
Why teams hire us.
Fixed price, not hourly
Every project gets a fixed quote in the Roadmap phase (week 2). No hourly billing, no surprise invoices, no scope creep charges. We align on price before we write a line of integration code.
Senior engineers only
Every engineer at IRPR has 10+ years of experience building production integrations. We do not use junior developers or offshore teams. You get a lead engineer who can architect, code, and deploy the entire integration.
Completed 200+ integrations
We have shipped over 200 integrations across healthcare, fintech, ecommerce, and logistics. Our team has worked with Stripe, Salesforce, HubSpot, Epic, NetSuite, Twilio, and 50 other APIs.
Compliance built in
We follow HIPAA for healthcare data, PCI-DSS level 1 for payment data, and SOC 2 controls for SaaS. Every integration is designed to pass an audit from day one.
Code you own completely
All source code lives in your repository from the first commit. There is no proprietary framework, no license key, no lock-in. Your team can take over maintenance immediately after we deliver.
We ship fast and on time
Our process delivers a production-ready integration in 8-12 weeks. We maintain a 98% on-time rate. We do not take projects we cannot complete on schedule.
Idea → Roadmap → Product → Release.
Every engagement runs through the same four-stage pipeline. Predictable by design.
